    Set Barbican api to listen on the right IP address

    Currently barbican-api will be listening on IPv4 address after
    bootstrap even for IPv6 labs. This will result in connection to
    barbican service internal endpoint refused, and unlock controller
    failed on IPv6 labs.

    This commit updated barbican puppet manifest so that
    gunicorn-config.py get updated to have the right bind IP address
    when started.

    Test Plan for Debian:
    PASS: package build, image build, installation on IPv6 lab
    PASS: after boostrap, observe barbican-api is listening on mgmt
          IPv6 address
    PASS: after boostrap, curl to barbicna-api internal endpoint is
          successful
    PASS: controller unlock successfully
